Possible to reserve 0 from various testing I have done yet that could cause the obvious side effect of achieving zero disk space:) Have only tested in development environment, however. Yet there are various tuning white papers and other benchmarks where the very same has been tested.

Thanks.

the parameter: dfs.datanode.du.reserved is used to reserve disk space PER datanode. Is it possible to reserve a different amount of disk space per DISK?
thanks
